Suwaid bin Ghaflah reports that Sayyiduna Umar (may Allah be pleased with him) while delivering a sermon at "Jabiyah" said that the Messenger of Allah (peace and blessings be upon him) forbade (men) from wearing silk, except for an amount equal to two, three, or four fingers, and while saying this, Sayyiduna Umar (may Allah be pleased with him) also gestured with his palm.
